It mounts directly to a host contactor to provide additional signaling or interlocking contacts in control circuits. Electricians and industrial maintenance technicians install this switch where expanded contact capacity is required without replacing the primary contactor. The unit weighs 0.044 pounds, making it a compact add-on that does not significantly change the footprint of the host device.\u003c\/p\u003e\n\u003cp\u003eThis auxiliary switch is suited for use in motor control centers, panel boards, and industrial control enclosures where contactors or control relays require additional contact blocks. It is appropriate for both light commercial and industrial applications where reliable status signaling, interlocking, or auxiliary circuit control is needed. The compact dimensions allow installation in tight enclosures where space is limited.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDirect-mount auxiliary switch block for compatible SIEMENS contactors and relays\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.044 pounds for easy add-on installation\u003c\/li\u003e\n  \u003cli\u003eProvides supplementary contacts for signaling or interlocking control circuits\u003c\/li\u003e\n  \u003cli\u003ePackaged individually, one unit per pack\u003c\/li\u003e\n  \u003cli\u003eDimensions of 4.803 inches x 3.504 inches x 1.496 inches for straightforward fitment verification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style auxiliary contact block for use with compatible SIEMENS contactors and control relays.
